Demonstrates that lozenges with L. reuteri Prodentis had both short- and long-term effects on periodontal disease

(additional results of the Tekce et al. 2015 trial)

Results

  • Pocket depth, plaque, and gingival indices, and bleeding on probing were all significantly improved (p<0.05) compared to placebo, at all time points
  • Significant changes up to day 180 of cytokines in gingival crevicular fluid: reduced MMP-8 and increased TIMP-1 levels (p <0.05)
  • Attachment gain was significantly greater in the L. reuteri Prodentis group compared with controls,
    on days 90, 180, and 360 (p<0.001)

Conclusion

Lozenges with L. reuteri Prodentis may be a useful supplement in moderately deep pockets of patients with chronic periodontitis

Facts

  • Study design: Prospective, randomized, double-blind and placebo-controlled
  • Subjects: Thirty (30) adults with chronic periodontitis, mean age 42 years
  • Dosage: 2 lozenges daily (4 x 108CFU/day)
  • Duration: Probiotic supplementation for 21 days, initiated after periodontal therapy. Clinical and biochemical evaluation at baseline and days 21, 90, 180 and 360.
  • Primary endpoint: Pocket depth reduction
  • Secondary endpoints: Changes in plaque index, gingival index, bleeding on probing, gingival crevicular fluid volume, attachment gain, and changes in MMP-8 (matrix metalloproteinase-8) and TIMP-1 (tissue inhibitors of matrix metalloproteinase-1). The balance between these two cytokines are essential for the degradation and remodeling of the extracellular matrix proteins.
